Screen Artifacts and no HDMI

[Thomasvdalen]

Hi.

I need some help of from the experts, i have asus x75a hm70 chipset with a sandy bridge intel 2370m hd3000 devid 0116.

I can get qe/ci oob with only adding duallink to my dsdt. I cant get hdmi working (only on low res 640x480) any higher and im getting a black screen. I also have artifacts, (randomly) sometimes its just working normal and sometimes with artifacts. my dsdt is in the attachment, 8

Im using smbios 8,1

Here are my files

i also dont know which patches i have to use on Olarila.com/forum/patches.php do i need the core sandy bridge patches or the core ivy bridge patches?

The interal display is working fine only the artifacts, is that code for external display? and have to put in boot.plist?

EDIT: Tried that, nothing changed
